Q:Why does the precision casting factory not usually make iron castings?

The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

Q:Cause of choking of casting parts

Choke fire is the process of pouring a large number of gases can not be discharged smoothly, boiling in the metal liquid, resulting in a large number of castings in the pores, and even incomplete casting defects

Q:How about casting parts for a year?

3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.

Q:What is the ejection angle of the die casting (Tan Gang)?

Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough

Q:How to get rid of casting sand inside casting parts?

Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

Q:Domestic large steel castings factory which is better, recommend!

Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good. At least spend money on research and development, then the quality should be all right.

Q:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?

According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner

Q:How to solve casting defect casting?

Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire

Q:Is the cast steel a casting part?

Cast steel is one of the casting parts that you call. The material is made of carbon steel or alloy steel, stainless steel, etc. the method is cast

Q:Can the casting part be phosphating with the phosphating solution of the pickling board?

Phosphating. But it's not necessary. Because casting parts have strong corrosion resistance.
